Inside your body, blood flows through tiny tubes called blood vessels. Sometimes, these tubes get all twisted and messy in one spot — that’s called an AVM, or Arteriovenous Malformation. It can cause problems, such as headaches or even bleeding, if not treated.
To fix it, doctors use a special method called Endovascular Embolisation. This method repairs the AVM from within the body, eliminating the need for large incisions.
First, the doctor helps you fall asleep so you won’t feel anything. Then, they gently slide a soft, thin tube into a blood vessel, usually in your leg. Using pictures on a screen, they guide the tube to the location of the AVM.
When the tube is in the correct position, the doctor inserts a small amount of special material, such as glue or soft plugs, to block the twisted vessels. This prevents blood from flowing in the wrong direction and helps prevent further complications. Once the AVM is blocked off, the doctor slowly removes the tube, and you rest in the hospital to recover.
This way, your blood flows more efficiently, and the risk of serious issues, such as bleeding, decreases.
- Stroke or transient ischemic attack (due to clot or vessel spasm)
- Vessel perforation or bleeding
- Headache, nausea, or temporary neurological symptoms
- AVM recurrence or incomplete obliteration
- Allergic reaction to contrast dye (rare)
- Minimally invasive and performed through a small catheter — no large incision
- Reduces AVM size or bleeding risk prior to surgery or stereotactic radiosurgery
- Can relieve symptoms like headaches or seizures
- Suitable for deep-seated or surgically inaccessible AVMs
- Often used as part of a multimodal AVM treatment plan
